echel0n 0d9fbc1ad7 Welcome to our SickBeard-TVRage Edition ...
This version of SickBeard uses both TVDB and TVRage to search and gather it's series data from allowing you to now have access to and download shows that you couldn't before because of being locked into only what TheTVDB had to offer.

Also this edition is based off the code we used in our XEM editon so it does come with scene numbering support as well as all the other features our XEM edition has to offer.

Please before using this with your existing database (sickbeard.db) please make a backup copy of it and delete any other database files such as cache.db and failed.db if present, we HIGHLY recommend starting out with no database files at all to make this a fresh start but the choice is at your own risk!

Enjoy!

class IterativeMatcher(object):
def __init__(self, filename, filetype='autodetect', opts=None):
"""An iterative matcher tries to match different patterns that appear
in the filename.
The 'filetype' argument indicates which type of file you want to match.
If it is 'autodetect', the matcher will try to see whether it can guess
that the file corresponds to an episode, or otherwise will assume it is
a movie.
The recognized 'filetype' values are:
[ autodetect, subtitle, movie, moviesubtitle, episode, episodesubtitle ]
The IterativeMatcher works mainly in 2 steps:
First, it splits the filename into a match_tree, which is a tree of groups
which have a semantic meaning, such as episode number, movie title,
etc...
The match_tree created looks like the following:
0000000000000000000000000000000000000000000000000000000000000000000000000000000000 111

[XCT].Le.Prestige.(The.Prestige).DVDRip.[x264.HP.He-Aac.{Fr-Eng}.St{Fr-Eng}.Chaps].mkv
The first 3 lines indicates the group index in which a char in the
filename is located. So for instance, x264 is the group (0, 4, 1), and
it corresponds to a video codec, denoted by the letter'v' in the 4th line.
(for more info, see guess.matchtree.to_string)
Second, it tries to merge all this information into a single object
containing all the found properties, and does some (basic) conflict
resolution when they arise.
